摘要: 分析了地震波在地下岩层中的传播路径、传递过程中能量的耗散以及在不同介质间传递时能量的损失,讨论了基于地震强度、震源深度、震中距等地震要素的能量对桥梁的作用,得出了反应能量与地震惯性力的关系式;分析了不同地震要素对能量的影响和变化趋势,提供了地震能量通过介质载体传导对桥梁的地震作用的分析途径。

Abstract: The seismic wave transfer path in the subterranean and energy dissipation in the process of transfer as well as the energy loss passing between different media were analyzed.The effect of the energy of earthquake elements,including the seismic intensity,focal depth and the distance of the epicentre,on the bredge was discussed.The relational expression between response energy and the force of seismic inertia was obtained.And the effect and changing trends of different seismic elements on the energy were analyzed,which provided the analysis approach that the seismic energy transferring through the medium could exert seismic effect on the bridge.

Key words: bridge engineering, seismic elements, energy transfer, changing trends
